FIREPROOF FLOOR AND CEILING.

SPECIFICATION forming part of *Letters Patent No. 601,036, dated March 22, 1898.

l Application filed December 9, 1896. Serial ll'o.` 615 ,070. (No model.) Y

To all whom gt may concern: v

i Be it known that I, YHORACE B. GAMB, of Akron, Summit county, Ohio, have invented `certain new and useful Improvements in Fireproof Floors and Ceilings; and, I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in iireproof iloors and ceilings; and it consists,

essentially, in a construction that not only lthree wooden timbers that are arranged horizontally and parallel and a short distance apart. Said timbers bear the iioor B, that is llaid upon and secured to wooden strips C,

suitably secured to the top and central portion of and arranged parallel with said timbers. Each timber A is rendered fireproof by skewbacks that cover the sides and overlap the top and bottom of the timber. Each of said skewbacks at its upper end is flanged laterally and inwardly, as at D', over the top I of the beam or timber and has the inner lon-l gitudinal edge of said flange D abutting the above its lower iiange D2 is provided withv a Iiange or shoulder d, that abuts the Opposing side of the lower portion of the supporting-timber, and the outer side of each skewback slopes downwardly and outwardlythatv is, the opposing sides of the skewbacks between two timbers diverge toward their lower ends. Wedge-shaped tiles or key-sections E, that are wider at their upper ends, are introduced between'the opposing sides of the skewbacks between the supporting-timbers, and upon driving said wedge-shaped tiles downwardly into place between the two skewbacks the timbers that support said skewbacks are effectually braced apart and thereby dispense with what is known as bridging for stiffening iioors. Each skewback, it will be observed, bears laterally against the supporting-timbers at its upper and lower ends. The depth of a wedgeshaped tile is preferably such that said tile when driven downwardly into place has its lower surface ush with the under surface of -iianges D2 of the skewbacks, so that said surfaces forma horizontal uniform ceiling.

I would here remark that I am aware that the state of the art already comprises fireproofl ceilings and floors in which a iiat course of blocks or tiles composing a flat arch,- so

called, is combined with skewbacks resting on suitable portions of floor-supportin g beams and that skewbacks having flanges overlapping the upper and lower heads of I-'beams have heretofore been employed. I do not, therefore, wish to be understood that my invention comprises more than that illustrated inthis application; and

Vhat I claim, therefore, is-

l.' Afireproof Hoor-and ceiling, comprising floor-supporting timbers arranged parallel with each other and at a suitable distance apart, skewbacks for covering the sides of said timbers, each of said skewbacks having at both its upper and lower end an inwardlyprojected flange, the outer and inner side face of each skewback diverging downwardly, thus leaving an air-space between the timbers and inner face of each skewback, substantially the entire length and height of the timber, wedge-shaped tiles arranged alternately between and in contact with the outer side face of each skewback, and floorbearing strips secured to the uppery surface of each timber and between the inner faces of the flanges projected from the upper portion of the skewbacks, substantially as shown and described.

2. In a fire proof-floor construction, the

TOO`

skewbaek D having` both its inner and outer side faces diverging downwardly to provide an air-space between the timber and inner faee of the skewbaek substantially the entire height of the timber and provided with ianges D D2, and each skewbaek havin g an integral inwardly-projeeted shoulder (Z located a short distance above the flange D2, whereby the timber is prope1'l57 Centered and secured at the lower portion thereof, sub- 1o stantially as shown and described.

In testimony whereof I sign this specification,in the presence of two witnesses,this 30th da1 of November, 1896.
